SCIENTIFIC APPROACH-BASED OF INTERACTIVE LEARNING MEDIA TO IMPROVE MATHEMATICAL THINKING SKILL AND SELF-REGULATED LEARNING

The aim of this research is to write a learning book and to develop a software of interactive media based on scientific approach to facilitate students in discovering concept, improving their mathematical thinking skill, and self-regulated learning. This is a two-year Research and Development, whereas in the first year is to write textbooks, and develop a interactive media software. The second year is to measure the validity of the entire instrument, the pre-test and post-test mathematical thinking skill, implement the software in a learning process, distribution a self-regulated learning questionnaire, implement the software in a learning process, explore the students’ perception towards this software through interviews. The sample of this research is seven grade students of junior high school in Tasikmalaya. Two schools are selected randomly. The developing of this software complies of stages: concept, design, material collecting, assembly, testing, and distribution. The validity test of all instrument used consists of consideration of two experts (a mathematician and learning-media expert); revision based on advices and input from both experts, empirical trial test, revision further if necessary. Based on the results of consideration two experts of instructional media and mathematician, test empirically, and perceptions of students that textbooks, textbook and software interactive learning media based approach to scientific, worthy implemented in the learning of mathematics students at the junior high school

Developing Online Learning Application for Programming Language

.Online learning is one of the most practical and promising learning alternatives nowadays. Flexible time and low cost of online learning are advantages that offline learning does not have. In addition, in online learning, each student can enrol the material according to their level, interest and abilities.  This study aims to build an online learning application for programming language. The method used in this study was Scrum software development. Scrum is one of the Agile method in software development. The system design using use case diagram resulted 3 actors and 8 use cases. The product backlog resulted in this study was five backlogs. The sprint composed based on product backlog result 4 sprints in total 120 days’ work. All five product backlogs were built successfully using Scrum. This system can be an alternative in learning programming language that offers the flexibility to the student, based on their ability and time

Health and safety implementation in Indonesia and risk of COVID-19

The COVID-19 pandemic impacted the socio-economic sectors since the end of 2019. Indonesian’s Government issued the large-scale social restrictions policy to limit the industrial activities. This study aimed to investigate the difference of the health, safety, and environment (HSE) implementations among Indonesian companies, before and during the disruption risk of COVID-19 pandemic according to the use of personal protective equipment (PPE). It used a random sampling, involved 1,027 workers from various sectors of Indonesian companies. Hypothesis tests used are ANOVA and t-test method. The level of HSE compliance changed quite significantly when the COVID-19 outbreak emerged. The results explained, there is no significant difference in HSE compliance based on company location, company risk level, and position of a respondent in the company. However, there is a significant difference between companies that have a HSE division and a HSE Management System certificate with the company who did not have any. The recommendations of HSE improvement formulated using a Safety Model Canvas and a Focus Group Discussion conducted to convey the jazz scenario in the next normal. This study suggests the priority order for HSE improvement strategy in a company is commitment, responsibility, engagement and involvement, leadership, competence, information and communication, to organizational learning

Internet Usage and Self-regulated Learning Assessment at Junior High School Students in Tasikmalaya City, Indonesia

Describes the pattern of relationship between internet usages on students, on the assessment of aspects of selfregulated learning. The aspect of self-regulated learning measured from 10 aspects. This study discusses the effects ofgender, the categories of schools (excellent schools and regular school), the total value of self-regulated learning andthe value of math exams. In brief, the research stages consist of three stages. The first stage of research is to createand retrieve the questionnaire data. The goal is to obtain all things related to internet usage, as well as measure aspectsof self-regulated learning assessment. The second stage of treatment on students. This treatment time is done for fourmonths, where students follow the math lesson with self-regulated learning method. Students provided with multimediadevices, textbooks and other. The third stage is the assessment or math test. The analytical method used is qualitativemethod with descriptive statistical approach. The results obtained that the dominant male students using internet forgames tend to have greater Aspects of Finding and Utilizing Relevant Learning Resources. While female, tend to bedominant in aspects of Evaluating Learning Processes and Results. The average mathematical exam results, in studentswho often use the game tend to have a higher value, compared with other students who often use social media

Initial Dynamic System Design for Optimization of Gravity Irrigation Water Management (Open Gravitation Irrigation)

An expression of conflict in the field. To overcome this problem is a regulation of several parameters,including regulation of planting schedules and reduction of land area. The model of the irrigation water managementsystem used is based on the risk of land failure and the optimum area of land that can be planted. The parameters usedto overcome this problem are planting schedules, risk of land failure and factor k. The k factor is the ratio of wateravailability to water needs. The output of this system is optimal net benefit based on the optimal alternative irrigatedland area. The results of the formula will show the optimal amount of land area that produces optimal net benefitsbased on certain planting schedules and certain effective rainfall. This system will also show that optimization will beachieved if there is a water balance between the availability and needs of irrigation water. The system referred to inthis study is a dynamic system. The purpose of this study is to make a preliminary design of a dynamic system to optimizethe irrigation system of agricultural land. The results obtained in this study were in the form of feedback loops andinteractions between loops with each other in agricultural irrigation systems
